This makes us homozygous for that gene. Inbreeding makes it more likely for this to happen.

A phenomenon known as inbreeding depression —the reduced survival and fertility of offspring of related individuals—occurs in both plants and animals, showing that variation for heritable fitness traits occurs within populations. The occurrence of inbreeding depression varies across species. Charles Darwin, British naturalist famous for his theories of evolution and ...A rule of thumb derived from agricultural systems is that an increase in inbreeding by 10% leads to a reduction in fitness components of ∼5-10% [. 46. ]. Thus, mating among first-degree relatives ( Fi =0.25) is only expected to reduce fitness components by 15-25%.Inbreeding: Inbreeding refers to the mating of closely related animals of the same breed.

Recessive Traits. weather forecast for jamestown new yorkantique hope chest value The slopes of these lines tell us exactly what this "cost-benefit" ratio is. For these breeds, those slopes are about 0.1, which means that an increase in inbreeding of 10% reduces litter size by about 1.
